Seamless Indoor-Outdoor Living, Built to Last
Infinity patio doors are built with Ultrex® fiberglass, a material engineered for superior strength and stability. It resists warping, cracking, and swelling far better than vinyl or wood, helping doors operate smoothly and maintain tight seals for decades.
Fiberglass frames combined with high-performance glass help reduce heat transfer and drafts. This improves indoor comfort and energy efficiency, keeping homes cooler in summer, warmer in winter, and more comfortable through seasonal temperature changes.
The strength of fiberglass allows for narrower frames and more glass, creating larger views and more natural light. Infinity patio doors are ideal for connecting indoor living spaces with outdoor patios, decks, and backyards.
Infinity fiberglass patio doors are designed to look great with minimal upkeep. Factory finishes resist fading and wear, eliminating the need for frequent repainting or refinishing while delivering long-term durability and value.
Patio Door FAQs
What types of patio doors are available?
The most common patio door styles include sliding glass doors, French (hinged) patio doors, and bi-fold doors. Sliding doors are popular for space-saving operation and wide views, French doors offer a more traditional look, and bi-fold doors create large, open transitions between indoor and outdoor living spaces. The best choice depends on your home’s layout, architectural style, and how you use the space.
Are new patio doors energy efficient?
Yes, modern patio doors are designed with energy efficiency in mind. High-performance glass packages, Low-E coatings, insulated frames, and improved weatherstripping help reduce drafts and heat transfer. Upgrading an older patio door can significantly improve comfort and lower heating and cooling costs.
Do patio doors require permits in California?
In many California cities, replacing a patio door may require a permit if the opening size is changing or structural modifications are involved. Local building departments often require inspections to ensure safety, energy compliance, and proper installation. A professional installer can help guide you through permit requirements and city-specific regulations.
Trusted by Infinity by Marvin

Marvin doesn't hand the Infinity name to just anyone. Choosing the right contractor is what separates a product that performs as engineered from one that doesn't, which is why Infinity by Marvin selected Custom Exteriors Inc. as their trusted dealer for the Bay Area. Decades of hands-on experience with Bay Area homes, proven installation practices, and deep product expertise made Custom Exteriors the partner Marvin trusts to represent the Infinity line, from fiberglass entry doors to windows and siding. Our local team of remodeling experts understands how these materials behave in our climate and installs every system with the precision and attention to detail Marvin's standards require, the same standards that make for a smoother remodeling experience and an exterior upgrade homeowners can count on for years.
That standard shows up in the details Marvin looks for in a dealer: installing the appropriate weather barrier to protect energy efficiency and the building envelope, and meticulously aligning seams and applying caulking for a clean, long-lasting finish. It's this level of craftsmanship, handled by trained experts on every single project, that earned Custom Exteriors its place as a Marvin-selected dealer, and that ensures your window, siding, or door delivers the long-term durability Infinity is known for.
